npm install errors / gulp no command known

soup

I get the following when trying npm install - any ideas?
Or is this a known problem

@soup said:

Seems you dont have python installed.

This thread has some solutions.

If you do have python installed make sure its not too deep (ie the path to it is not too long).

Again comments at the bottom of the below thread talk about how to fix this problem

Thanks @dazmiller , node-gyp is unstable on Windows (https://github.com/nodejs/node-gyp/issues/629) , so it is a known problem. I found some links that might be helpful for you @soup:

Actually the install python (have used version 2.7.3) seems to have done the trick.
Installed python, run the command
npm install

then (you get a warning about lodash)
npm install --global gulp

then run the command
gulp

and wow my scss file now actually gets converted to css
Super, thanks for the help peeps

@soup: You're so lucky. I think you are on Windows 10, and Microsoft listens and updates the OS constantly. I will make Laragon more convenient to Nodejs related projects.

soup

Nope still on Windows 7 here
...and amazed that its actually working too

leokhoa

Thanks for let us know. Like I said you are so lucky

I had the same issue except it was due to the fact that npm install couldn't run properly due to windows long filenames.

If Laragon isn't installed onto your drive root you might end up in the same situation I was. I fixed it by making a symlink to my installation folder.

cd c:
c:
mklink /D [project name] [path to laragon project folder]

Simply replace le brackets with the proper project name and full path.
Hope this can help someone else that is unable to fix the issue by simply running @soup solution.

Seems to be an issue with NPM more over than Laragon.
